Title: Improvements in or relating to glass feeding machines
IPC: C03B7/086
Filed: 1927-02-19
Abstract: 274,370. United Glass Bottle Manufacturers, Ltd., and Tipping, J. Feb. 19, 1927. Delivering molten metal.-Relates to a feeder of the reciprocating plunger type and consists in providing means for independently varying the time and stroke of the plunger and for independently timing the action of the shears, so that successive " gobs " of different weights and in a particular order may be delivered to the forming- machine. The device is shown in sectional elevation in Fig 1 and in plan in Fig. 2. The plunger P, which expels the " gobs " of metal through an outlet in a forehearth, is attached to a rack m<6> which is engaged by a pinion m<5> on a shaft m. This shaft is connected by shafting and bevel gearing with a pair of meshed pinion wheels m, m<1>, Fig. 2, secured on vertical shafts M, M<1>, respectively. on each of which a number of superposed fingers or levers, L<1> and L'x are mounted. A number of superposed driving-cams A-D are mounted on a vertical shaft G, Fig. 1, between plates E, F, and are positioned adjacent to the shafts M, M<1>. Each cam consists of an annular member having internal teeth, external projections a<1>, Fig. 2, and rollers a. The shaft G is driven from the machine for forming the glassware. The plates E,F, carry shafts K<1>, Fig. 1, each of which carries two pinion wheels. One of these pinions, k<1x>, engages with the internal teeth of a cam and the other, k', engages in a toothed recess in the plate to lock the shaft By lifting one of the shafts K<1> so that the pinion K<1> passes out of engagement with the recess in the plate E, a cam can be advanced or retarded relatively to the others. Each of rollers a on a cam engages in succession a pair of the levers L<1> and L<1x> and thereby causes a reciprocation of the plunger P. Each lever may be rotated relatively to its shaft, and the lower end of each lever may be moved relatively to its hub. Thus the adjustment of the cams and the levers enables the length of the stroke of the plunger, the time taken for the up and down strokes, the dwell between the up and down strokes and between successive reciprocations, to be varied so that a succession of " gobs " of different weights can be delivered from the feeder. Shearing. The shears are operated by the piston of an air cylinder R, and the operation is controlled by a series of bleeder valves Q which are connected by flexible tubes r and pipes r<1>, r<2>, with the control valves of the cylinder R. The bleeder valves Q are in pairs, of which one valve controls the opening of the shears and the other, controls the closing. These valves are mounted on arc-shaped supports q<1> and are operated by the cam projections a'. The valves can be adjusted on their supports, so that the time of opening and closing of the shears, and the interval between them, can be adjusted for each " gob." If desired, the shaft G can be driven by a motor, and other driving-cams can be provided for controlling the movements of an air-driven forming-machine.

Title: Improvements relating to photometers
IPC: G01J1/60
Filed: 1934-02-14
Abstract: 433,385. Determining photographic exposures; pupilometers. HILTPOLD, W., 14, Forchstrasse, Zurich, Switzerland. Feb. 14, 1934, No. 4958. [Classes 97 (i) and 98 (i)] A pupilometer comprises a sheet 1 bearing a series of dark circles of diameters decreasing from the maximum size of the pupil of the human eye to the minimum, and adapted to be held close to the user's eye to compare the pupil size with the circles. As the diameter of the pupil is a function of the intensity of the light shining thereon, the number in the series of the circle of equal diameter with the pupil furnishes an indication of the exposure time required for a photographic camera. The eye and the circles may be compared in a mirror 3 attached to a case 4 which holds the card 1 when the latter is not in use. The back of the card bears graphs for the calculation of exposure time from pupil size. Alternatively the card may bear an exposure scale 5 and have a sector 8 and disc 10 rotatably attached to it. It is found that corrections for different normal pupil sizes may be made by addition or subtraction of a fixed quantity. The sector 8 therefore bears a scale 9 numbered in accordance with the series of circles and by fixing the sector at various angles on the card 1 corrections for different normal pupil sizes can be made. The disc 10 bears a film sensitivity scale 11 and a diaphragm scale 12. When the desired sensitivity point on scale 11 coincides with the observed circle number in scale 9, the exposure time on scale 5 will coincide with the diaphragm opening on scale 12. An additional scale 6 is provided on the card 1 if a filter correction is also required. The circles may be arranged on a circular edge of card 1 and a member 21 may cover them, a recess 23 enabling one circle to be seen at a time. Specification 342,236 is referred to.

Title: Improvements in or relating to tetrahydrofurfuryl esters of 2-methyl-4-chlorophenoxyacetic acid as a herbicidal agent
IPC: C07D307/00
Filed: 1953-02-24
Abstract: The invention comprises the tetrahydrofurfuryl ester of 2-methy-4-chlorophenoxy-acetic acid.  This compound is obtained by the condensation of 2-methyl-4-chlorophenoxy-acetic acid and tetrahydrofurfyl alcohol in the presence of an esterification catalyst such as phosphoric and p-toluene sulphonic acid, an example of such a condensation being given.  The products are useful as ingredients of compositions for the control of vegetation growth (see Group VI).ALSO:Herbicidal compositions comprise as an active ingredient the tetrahydrofurfuryl ester of 2-methyl-4-chlorophenoxyacetic acid, the preparation of which is described (see Group IV (b)).  The ester may be compounded with inert carriers such as talc, soapstone, Frianite, pyrophilite, Attapulgas clay, chalk, volcanic ash and preferably with a water-soluble and/or oil-soiluble emulsifying or wetting agent.  The compositions may be in the form of a concentrate for dilution with an additional amount of powdered carrier or in the form of a wettable powder which may be formed into an emulsion with water or mineral oil.  The ester may also be used in solution in organic liquids or as an aqueous emulsion with surface active ionic and/or non-ionic agents. Dilution in spray oils or petroleum oils such as Diesel oil or kerosene may be effected using a mutual solvent such as aliphatic esters, ketones and aromatic hydrocarbons or oxygen containing derivatives.  Other active ingredients such as 2, 4, 5-trichlorophenoxyacetic acid derivatives, insecticides and fertilisers may be incorporated.  Concentrations of 0.04 to 4 per cent. by weight, based on the acid from which the ester is derived are referred to.  In an example, 2-methyl-4-chlorophenoxyacetic acid tetrahydrofurfuryl ester is dissolved in kerosene and xylene and an alkyl aryl polyethylene glycol ether and a sodium mahogany sulphonate are added to give a phytocidal concentrate which is soluble in petroleum oils or can be emulsified in water. Individual emulsifiers and aliphatic or aromatic solvents can be used.

Abstract: 1,102,181. Binary to binary-coded-decimal converters. INTERNATIONAL BUSINESS MACHINES CORPORATION. 27 Jan., 1966 [6 Feb., 1965], No. 5249/65. Heading G4A. [Also in Division H3]  In a binary to binary-codeddecimal converter, the input bits are supplied serially to an accumulator register and any correction necessary to convert those already arrived to binary - coded - decimal is effected by settable correction devices before the next bit arrives. The converter is under control of two oscillatordriven ring-counters (Fig. 3a, not shown) producing in one complete cycle, eight bit-time clock pulses, B o  to B 7 , and four other clock pulses A, R, E, S during each bit-time dividing it up. Referring to Fig. 5, the first bit-time clock pulse B o  resets the seven triggers T 1 , T 2 , T 4 , T 8 , T 10 , T 20 , T 40  of an accumulator register. During the next five bit-times, B 1  to B 5 , the first five binary input bits are read into respective ones of the triggers T 1 , T 2 , T 4 , T 8 , T 10 . If the sixth input bit is used as a check bit it is deleted and the seventh bit read into the next trigger T 20  during the seventh bit-time B 7 , otherwise the sixth bit goes into trigger T 20  during the sixth bit-time B 6 . As each bit is entered, and before the next bit arrives, logic circuitry responsive to the input bit arriving and the above triggers detects whether the number so far entered (including the bit currently arriving) is in binary-codeddecimal form and sets one of two correction triggers 31, 32 if not. The two correction triggers cause addition of six and twelve respectively into the accumulator register, in each case in two stages viz. 4 plus 2 and 10 plus 2, the correction trigger then being reset, all before arrival of the next binary input bit. Carries propagate in the accumulator register automatically. After conversion, the contents of the register are read out to relays, e.g. 51.

Title: Improvements in or relating to automatic circuit breakers, especially those adapted for use in connection with electric track protection
IPC: H01H71/68
Filed: 1924-03-03
Abstract: 231,993. Igranic Electric Co., Ltd., and Rantzen, M. J. March 3, 1924. Protective arrangements for use especially in connection with electric tracks comprise an overload circuit-breaker and means for preventing subsequent establishment of the line should the total resistance thereon rise above a given amount (for instance, if someone picked up the broken line), together with means whereby, during the interruption, a resistance is connected on the line in parallel with the load, its value being low enough to ensure the former means not operating except as the result of breakage of the line. Fig. 1 shows an application to a manually-closed breaker, wherein a generator 1 feeds, for example, an overhead tram-line a and load 29 through an overload relay 9 and breaker 12, the former on overload lifting a lever 26 to open the breaker. The line is earthed through a relay 18 which is de-energized on disconnection of the line to earth the latter through resistance 19. A Wheatstone Bridge is thus established having as three arms the resistances 22 - - 24 and as the fourth the resistance of the line a, the resistance of the load 29 and the resistance 19 in parallel therewith, and the earth return. The Bridge is fed at the points 33, 32 through the closed switch 27 and across the balance points 34, 35 is the coil 16 of a polarized relay adapted, if the value of the fourth arm is above a predetermined value (as it would be if a member of the public picked up a broken end of the line a), to close the circuit of a lockout coil 25 and prevent reclosure of the breaker 12. The relay contacts may be adapted to be manually reset, or to open automatically on decrease of line resistance. Fig. 2 shows an application to an automatically re-closing breaker having a closing coil 13 fed by a bridging resistance 11, its circuit including a maintaining resistance 3 shorted by a lever 4 under control of a dashpot 5, and contacts 36 of a relay 37. Operation of relay 9 de-energizes the coil 13 and opens the breaker and parallel circuits are established from the resistance 11 through coil 2 to earth and contact latch 8, contact 7, and line a to earth, so that if the load is excessive, the coil 2 will be prevented from operating. On removal of the - overload, however, the latch 8 is released by the coil 2 and the Bridge is fed through the contact 6, the breaker, if the line is unbroken, reclosing when the dashpot 5 has moved sufficiently to allow the lever 4 to short the resistance 3. If the broken line is picked up, the relay coil 16 will energize the relay 37 and open the circuit of the closing coil 13 at contacts 36, thus preventing reclosure till the relay is reset. On reclosure of the breaker, the lever 4 is again latched by the latch 8. In a modified form, the Bridge and relay may be replaced by a voltage coil similar to coil 2, the latter ensuring the load shall not be less than a desired amount, and the former that it shall not exceed another desired amount.
